Color Manager

DeprecatedKNIME Base Nodes version 4.3.1.v202101261649 by KNIME AG, Zurich, Switzerland

Colors can be assigned for either nominal (possible values have to be available) or numeric columns (with lower and upper bounds). If these bounds are not available, a '?' is provided as a minimum and maximum value. The values are then computed during execute. If a column attribute is selected, the color can be changed with the color chooser.

Options

Column(s):
Select the column whose possible values or ranges should be used for color selection.
Nominal:
Assigns colors based on the possible attribute values of the selected column. The colors are set independently for each attribute value.
Range:
Assigns a color gradient based on a numeric attribute. If the range is known, the minimum and maximum are displayed in the list, otherwise a '?' is shown. The color is determined by the position of the attribute's value within the numeric range: the corresponding color is set at the same position in the gradient.
Alpha:
Adjust the color's alpha component in the range of 0..255. Please note, alpha composition is expensive in cases when operations performed are not hardware-accelerated.
